Duplicate entries in Contacts

I have an iMac using Mountain Lion, an iPad 3 and iPhone 4. (Both IOS6). I have duplicates of Contacts and Calendar on my iPhone.
What have I done to cause this? how can I fix this?

If you are syncing contacts over the air with your MobileMe account on your iPhone, there shouldn't be any need to also sync contacts direct with the Address Book on your Mac via the iTunes sync process. Doing both will duplicate the contacts on your iPhone.
Under the Info tab for your iPhone sync preferences with iTunes, deselect Sync Contacts followed by selecting Apply.
On your iPhone, go to Settings > Mail, Contacts, Calendars.
Select your MobileMe account.
Turn Contacts off for over the air syncing. A warning message will be provided indicating this will delete all contacts downloaded from and being kept synchronized with your MobileMe online address book along with a prompt to save the contacts locally on your iPhone. Decline this prompt.
This will not delete the contacts on your iPhone that were synced direct with the Address Book on your Mac via the iTunes sync process.
After confirming that your contacts are correct in the Address Book on your Mac and with your MobileMe online address book by logging in to your MobileMe account via webmail access using a browser - the contacts are not duplicated with the Address Book on your Mac and with your MobileMe online address book, follow this by turning Contacts back on for over the air syncing with your MobileMe account on your iPhone. You will be provided a merge prompt which you want to select.
This should get rid of all duplicates on your iPhone.

Duplicate entries for contacts after BB update 10.2.1.2102

Hi,
This is in regards to my boss's blackberry q10.
I recently updated the OS to 10.2.1.2102 (done via phone update not via BB link).
After the update, i noticed that all contacts had a duplicate entry with only one of them containing the proper details while the other was blank. I have uploaded the pics through the dropbox link below.
pictures for BB Q10
If i delete the blank contact, it solves the problem but I have to do it individually for each contact.
Is there a better way of doing this? Would really appreciate your help here.
Thanks,
Brennan

If you open the blank one and go to the bottom and hit "Link" does it show what contact list the blank one is in?
Also, where was the source of the contacts to begin with? Did they come from an Exchange mailbox? Another email account? Wired sync from Link?

Duplicate entries in Contacts and iCal

I have Lion on my iMac and IOS 5 on my i Phone 4S. Ever since I set up iCloud, everything in Contacts and on iCal is entered twice. Do I have to do anything with iTunes to stop this? What else if anything do I need to do to stop this?

Actually, we never signed up for iCloud on the 3G iPhone. That said, I followed someone's suggestion in another post on deleted contacts. I clicked the little arrow on a recent number of a friend that had called and then selected 'Add to Existing Contact.' Somehow, with that action, all my contacts reappeared immediately. What an entirely strange glitch.
Still not sure what to do with the duplicate iCal entries but will check out the iCloud settings on the iPhone 4 to see whether that fixes the problem.

My family put multiple devices on the icloud, and I need to know how to manage duplicate entries. Specifically contacts. If I fix the contact list on my pc will it push the info out to the other devices and maintain it correctly?

All devices signed into the same iCloud account will finish up with the same contacts. Of course if prior to joining iCloud two family members each had an entry for Uncle Fred, then you will finish up with two contact cards for Uncle Fred, and so on. If you tidy this up on your computer then the changes will propagate to everyone else.

Duplicate entries in calendar and contacts

I have many duplicate entries in my calendar and my contacts. Deleting each one on my Z10 is very time consuming. Is there a way to do this more efficiently, such as viewing the calendar and the contacts as a file on my computer, where editing would be much easier?

Ok you can try one thing first, less invasive to see if it clears one set of contacts.
Open your contacts
Swipe down from the top edge > Settings.
Scroll down and turn off each of the various contact accounts.
tap BACK at lower left and now view your contacts.
All that should be left are the "local" contacts. Do you see any, and are they the contacts duplicated?
If so, then close all that and return to your main homescreen.
To clear the local calendar or contact database on the BlackBerry 10 smartphone, complete the following steps:
Swipe down from the top bezel on the home screen, and select Settings.
Select Accounts.
Tap the action menu button (3 vertical dots) on the bottom-right.
Select Clear Local Contacts or Clear Local Calendar.
Now, view your contacts app again. Make sure the ALL TAB is displayed at lower left.
Scroll through and check for duplicates.

How do I remove duplicate entries in my Contact List?

I imported my contact list from MS Outlook, but for some reason there are many duplicate entries in Thunderbird.

This add on claims to do what you want. I have never used it so I cannot comment on if it works.

Duplicate calendar entries missing contacts etc

Since i downloaded the update to V3 for iPhone i have noticed two calendar lists on the iPhone. One is from My Mac and the other is ****@mac.com. If i select 'all calendar's i get duplicate entries. If i select one or other i only get some entries plus on sync it keeps wanting to add or delete. I have now noticed that while i have all my contacts on the iPhone the majority are missing from the iMac and mobile me. This all started with the V3 download.
Help!

Ken,
Is your problem similar to this: macosxhints.com - About duplicate contacts and calendars on iPhone 3.0?

How can I get rid of duplicate entries in iPad iCal?

This is kind of a repeat and I apologize, but I have duplicate entries now in my iCa on my iPad because of iOS5? Others on this same topic said something about deleting the whole iPad calendar. Before I did that, I wanted to be sure, that if I delete the iPad calendar, it won't delete the iMac calendar. I'm just not sure how to get one one iCal entry in my iPad calendar. I have birthdays, etc. entered until eternity!

I notice the mail setting in iTunes is set to sync, but all the others are set at syncing with iCloud. What about mail? Should it be syncing with iCloud, iTunes, or both (I assume not both, but......). I still don't have mail working with iCloud anyway so I'm not sure what should be happening there.
I would be consistent with respect to the information in the "Info" pane in iTunes. That is, if you want to sync Calendars, Contacts, and email, use either iCloud for all 3 (e.g., enable all 3 in iCloud and deselect all 3 from iTunes) or iTunes for all 3 (select all 3 in iTunes and disable all 3 in iCloud).... don't break them up across services.

How to delete duplicate entries in address book

Is there an easy way to delete duplicate entries in Address Book?

I have an iPhone where I create new contact details and a MB Air running OX X 10.7.3
In Address Book I see duplicate entries across the whole book. The other day I was traveling without my MB and needed to urgently reach someone who's number I knew was in my iPhone contact list for sure but searched and search and couldn't find it.
Turns out that when I had been going through the Adress Book on the MB Air trying to eliminate some of the duplicates I had chosed --without even knowing it or realzing it-- the card that I guess sync with my iPhone. It was gone. Sure enough, when I got back and looked it up on the MB Air it was still there not syncing to my iPhone.
I have used Address Book / Card / Look for Duplicates ...
I have also followed the Help suggesting and pressed Control / select to highlight two duplicate cards and even though the First / Last / Company / phone numbers / etc. are all the same I get the message: "The cards could not be merged because they came from different accounts."
I have checked with guys from the office who have the exact same problem with no idea how to solve the problem.
Is it that in order to use Address Book on both an iPhone and an OS X machine you've just got to be smarter, more sophisticated, more IT oriented?
Seems like a pretty easy thing not to be struggling with.
I should mention that I was a Mobile Me subscriber and now use iCloud which I'm sure has something to do with all of this.
But it seems pretty basic to me. If I have an Address Book it should synchronize between OX X and IOS.

View Duplicate Entries in Address Book

Does anyone know how you can view your duplicate entries in Address Book before you merge them?
Thank you!

books06,
Welcome to Apple Discussions.
It depends upon which version of Address Book you are using, and your definition of "view."
1. Address Book 3.1.1 Help
2. Address Book 4.0.3 Help: Combining duplicate cards and information
To find and merge duplicate cards:
1. Choose Card > "Look for Duplicate Entries."
2. Address Book tells you if it finds duplicate cards, cards containing duplicated information, or both.
3. Click Merge to merge duplicate cards and remove redundant information on cards.
When Address Book merges duplicate cards, it creates a single card for the contact containing all of the unique information from each merged card. Address Book uses the picture from the merged card appearing first in the list.

Missing and duplicate entries in the calendar

I'm a long time (1997) Palm user who's moved to a BB 8330 last month. I can't seem to get calendar syncing to work correctly. In some instances, I am missing items on Outlook. I often have duplicate entries on the handheld. I've searched the forums and there seem to be similar issues and the solutions appear to be around Service Books, but I'm not confident I have a clue how not to lose lots of info.I also cannot seem to find information that explains the relationship between email addresses & calendar (I don't see why there should be any!!!)
Scenario (trying to answer up front the questions from other forum posts):
I am using Outlook on my home computer to manage my personal calendar. I do not have an email account associated with Outlook.I have set up 2-way sync with Outlook for calendar, tasks & contacts
My work uses Lotus Notes. I have set up one sync to the handheld only from the Lotus Notes calendar
The only email account configured on the BB is a gmail account (which is not associated with either calendar). I originally set this up via the wizard, then removed it, but added it back (under Email settings) when I discovered I couldn't send email from the Address book without it. I actually prefer google mobile for email management since it modifies the server state as well. Not sure if the add/remove/add sequence has somehow messed up the calendar?
I have checked under Calendar > Options and two calendars appear. Based on the color associations it appears that Device Default is associated with Outlook personal calendar & my gmail account is associated with the Lotus Notes calendar entries. As far as I know I did not create these associations.
Checking under Options > Advanced Options > Default Services, I see CICAL & CMIME entry and those are both the gmail account.
Checking under Options > Advanced Options > Service Book, I see only one CICAL & CMIME entry and those are both the gmail account.
Separately, I do have a couple of mobile apps to read email (gmail- same acct - and yahoo), but those appear to not integrate into the BB apps directly.
Everytime I sync with Outlook, I end up with lots of duplicate entries on the handheld. I have also noticed that I am missing entries that are on the handheld, but are not on Outlook (in one very odd case, the entry was created on Outlook and now only exists on the handheld). I may have deleted duplicate entries related to the missing items at one time... I can't be sure about that. I believe I currently have a complete calendar on the handheld, but not 100% confident I have a good calendar anywhere.
And as an aside, have to say I'm really bummed that I have lost easy access all my Palm historical data. It appears BB will not bring in old calendar data by design (found that in some BB documentation on their site). Now that I will not keep up with Palm upgrades, at some point I will lose access to that data. Sigh.
Any, all help appreciated.

Hello...correction:

Ok. In that case, try this. (That worked for me when I had similar problem. Ignore if you already tried this)
1) Turn off the phone
2) Remove the battary and place it again
3) Restart your phone
Have the BB ON (e.g., something showing on the display, the HomeScreen would be fine) when you remove the battery. That is the cleanest hard reboot method.
Good luck!

Deleting duplicate entries in iCal?

How do I delete duplicate entries in iCal (identical entries on the same date)?

Todd,
I suspected a more serious problem because the answer was too easy.
Thousands of duplicate entries...Is this what happened?
According to, Mac OS X 10.4: Stay away from the SyncServices folder: As if it were a swarm of bees, you should stay away from the SyncServices folder in Mac OS X 10.4. Removing or modifying anything in it—or in subfolders within it—may cause unexpected issues. (This folder is located in your Application Support folder, in your Library folder, in your Home folder.)
Deleting or modifying things in the SyncServices folder may cause unexpected results such as:
• Duplicate contacts in Address Book or appointments in iCal.
• Data loss in Address Book or iCal.
Important: Any lost or duplicate data could propagate to other devices and computers via iSync and .Mac sync. This means data could be lost on other computers.If that is your problem, I suspect that without a backup, duplicate entry deletion will at best be tedious, and at worst fraught with frustration. You may be better off starting from scratch.

How to avoide multiple duplicate entries in adress book?

How to avoide multiple duplicate entries in adress book? I can add the same contact name and number more than twice and the phone isn't warning me at all!!! I's quite a heck for me.

Finding duplicate entries in address book

I am using Address Book 5.0.3, where I have been using LinkedIn's CardMunch to import contact details via my iPhone. However, I now end up with three distinct issues regarding duplicate entries:
1/ two people with the same name, e.g. John Smith, but I know they are two separate people and they work for different companies.
2/ After an import, I may have some duplicate entries, say Alan Walker, who has moved from company A to company B and I want to replace his old contact details with the new information.
3/ two duplicate entries the same name, say Brian Vickers, both of which refer to the same person who still works for the same company, but has new contact details or additional data, such as a mobile number that I did not have before.
4/ two duplicate entries that are identical. E.g. I imported the same card twice for some reason.
5/ multiple entries marked 'Cannot Read Name', where CardMunch had a problem, but I know they are different people and I have to edit these to manually enter the correct information.
Unfortunately the Address Book find duplicates function, whilst it works, does nothing useful. The only option I am presented with is 'Merge', which in all of the scenarios above apart from item 4 I do not want to do a merge function - I want to either 'Mark as NOT Duplicates' (item 1/), 'Replace Selected Fields' e.g. show me the two cards side by side and allow me to select which fields from which card are to be kept, replaced or removed and then implement the merge (item 2), "Add New Information' but allow me to select the label for that information before merging so that if someone has a new iPhone, but is still keeping their old mobile, I can select the field label correctly and then merge (item 3) or 'Edit Card' which allows me to open any identified duplicate and add in missing information that would mean that it is no longer a duplicate item.
Can anyone suggest a way of doing this, or can Apple's developers please add these features to the Address Book App as soon as possible?
Thanks, Russ Taylor

SPWebConfigModifications Duplicate entries, applying to all Web Applications and not removing entries

Hi,
Hopefully someone can offer some advice, I may be missing something obvious here.
I'm currently trying to write a feature event receiver to apply web.config modifications that are required by a recent project.
The feature is web application scoped & it doesn't activate by default on deployment, currently testing with a very small addition isn't working at all, I've followed numerous posts about duplicate entries & items being removed, none of which have
helped.
Here is my code;
public override void FeatureActivated(SPFeatureReceiverProperties properties)
            SPWebApplication webApp = properties.Feature.Parent as SPWebApplication;
                SPWebConfigModification Modification = new SPWebConfigModification();
                Modification.Owner = "ConfigUpdater";
                Modification.Path = "configuration/appSettings";
                Modification.Name = "add[@key='Test']";
                Modification.Sequence = 0;
                Modification.Value = "<add key='Test' value='Server=TestServer;Database=TestDB;Trusted_Connection=True;' />";
                Modification.Type = SPWebConfigModification.SPWebConfigModificationType.EnsureChildNode;
                if (!webApp.WebConfigModifications.Contains(Modification))
                    webApp.WebConfigModifications.Add(Modification);
                    webApp.Update();
                    webApp.WebService.ApplyWebConfigModifications();
        // Uncomment the method below to handle the event raised before a feature is deactivated.
        public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
            SPWebApplication webApp = properties.Feature.Parent as SPWebApplication;
            Collection<SPWebConfigModification> modsCollection = webApp.WebConfigModifications;
            int count = modsCollection.Count;
            for (int i = count - 1; i >= 0; i--)
                SPWebConfigModification mod = modsCollection[i];
                if (mod.Owner == "ConfigUpdater")
                    modsCollection.Remove(mod);
            webApp.Update();
            webApp.WebService.ApplyWebConfigModifications();
Upon activation on 1 web app, the entry gets added twice to the web.config of every web application in the farm & upon deactivation the entries remain in the web.config files.
On activation, after this line, webApp.WebConfigModifications.Add(Modification); the webApp is updated to include the entry & only once, however 2 entries for it appear in the web.config files & as mentioned for every web application.
On deactivation, after updating the web app, the modification is removed, however it remains in the web.config files.
I'm wondering if the code actually works, as I can't see anything wrong & if there is some caching occurring somewhere which is applying the extra line/s upon calling ApplyWebConfigModifications.
Any help on this would be much appreciated.
Thanks,
James

Hi James,
Per my understanding, there is an entry gets added twice to the web.config file of every web application in the FeatureActivated event.
As a common practice, I suggest you debug your code to see how it works during the process, it will provide more information for a better troubleshooting.
Also, you can test the code in a Console Application to see if it will work as expected.
Thanks
